Sept. 11-12, 2017. The only sample we could obtain at this location during -normal work hours occurred on September 12, 2017. Between the time
the plant closed on the evening of the 1111 and returned on the 121 rve received approximately 3.25" of rain overnight. The plant manager"
immediately observed the discharge and obtained water discharge sample as directed by the corporate EHS manager. We are unable to determine
when the flow began the previous evening, the discharge, was a strong torrent. The lab analysis does identify a high TSS reading for process
wastewater but was still below stormwater discharge criteria.
A request for a second outfall will be made during November to reduce the volume and flow rate from outfoll 1. This will also allow us to increase our
storm surge capacity and maintain our discharge parameters more consistently.

Sept. 11-12, 2017. The only sample we could obtain at this location during normal work hours occurred on September 12, 2017. Between the time
the plant closed on the evening of the 111h and returned on the 121h we received approximately 3.25" of rain overnight. The plant manager
immediately observed the discharge and obtained a water discharge sample as directed by the corporate EHS manager. We are unable to determine
when the flow began the previous evening, the discharge was a strong torrent. The lob analysis does identify a high TSS reading for process
wastewater but was still below stormwater discharge criteria.
A request for a second outfall will be made during !November to reduce the volume and flow rate from outfoll 1. This will also allow us to increase our
storm surge capacity and maintain our discharge parameters more consistently.

2 Report the abbreviation for the type of Authorized Wastewater Discharges here: Vehicle and Equipment Cleaning (VE), Raw Material Stockpiles (RM), Mixing Drum
Cleanout (MD). Report more than one type if the waste -stream is commingled.
3If an effluent limit is exceeded twice in a row, the permittee is required to institute monthly monitoring for that parameter for six months, unless DWQ RD staff
notifies you to continue monitoring.
4 pH limits are 6-9 S.U. for wastewater discharges to freshwaters, and 6.8-8.5 S.U. for discharges to saltwaters.
5 TSS limits are 20 mg/L for wastewater discharges to HQW waters, 10 mg/L for Trout and PNA waters, and 30 mg/L for all other water classifications.
s Process wastewater discharges shall only be monitored for TPH when commingled with stormwater discharges from VMA areas. TPH does not have a limit for wastewater,
but instead is subject to benchmarks and provisions of Part IV, Section A, including the Tiered Response Action.
Flow rate can be measured continuously or calculated. Flow limits for wastewater discharges to HQW waters shall be set to 50% of the Summer 7Q10 Flow as per 15A
NCAC 02B .0224. Permittees who discharge wastewater to HQW waters shall obtain a Summer 7Q10 flow and report this information to DWQ. If the permittee cannot
